Hector Bellerin has added to Arsenal's defensive woes with the news he will miss Wednesday's Carabao Cup clash with Blackpool and is a doubt to face Liverpool this weekend.
Bellerin was substituted at half-time in Sunday's 2-2 draw with Crystal Palace, the 23-year-old replaced by Stephan Lichtsteiner.
The full-back is one of five Gunners defenders currently sidelined with injury, leaving coach Unai Emery with very few options ahead of two games in quick succession.
Bellerin suffered a right thigh injury at Selhurst Park and Arsenal have confirmed he will be assessed ahead of Liverpool's trip to Emirates Stadium on Saturday – where a win would move Arsenal to within one point of Jurgen Klopp's side.
